- F12 now properly hides the action buttons

- Changed the 'black overlay' you get when paralyzed, blind or in critical condition to include a small circle around you. It still 'blinks' once every 25 seconds or so.
- Added a flag BLOCK_GAS_SMOKE_EFFECT, which can be applied to masks, glasses and hats, which prevent gas smoke, which contains reagents, from having an effect on you. Currently only present for gas masks.
- Dramatically lowered the amount of damage you get per breath while in critical condition. Critical condition now lasts for about 5 minutes if nothing is causing you any additional harm. This in combination with the new black image overlay is an attempt at making doctors more willing to help. For one thing they'll have more time to get to you, for another you will get to see if they murder you before sending you to genetics.
- Added Cheridan's wooden chairs to code
- Added a action_button_name to all items, which defaults to null and contains the text which appears on the action button. If an action button exists, but this variable is not set, the text will default to 'Use [name]', name being the name of the item tied to the button.
- Fixed the problem which resulted in certain glasses types making you keep night vision abilities even after you took them off.
